Some journal web sites state that the journal is indexed DOAJ when it is not. Often, the home page carries the DOAJ logo along with logos from other indexing services. Even though we write to these journals, there is no guarantee that they will remove our logo.
I advise you to ALWAYS check at https://doaj.org that a journal is indexed in DOAJ even if its web site carries the DOAJ logo or says that it is indexed. You can never be too careful and it only takes as long to check as it takes to type the journal name or ISSN into the DOAJ search box and press Return.
If you spot a journal that is carrying the DOAJ logo but is not indexed in DOAJ, I would love to hear from you!
